Abstract

CIE 191:2010 recommends a mesopic photometry system that defines the spectral luminous efficiency function for peripheral visual tasks. For implementation of the system, the visual adaptation field, which takes into account the surrounding luminance effect to the adaptation state, needs to be determined. For the definition, a series of vision experiments has been conducted in order to measure the high luminance source effect to the adaptation state at a peripheral task point in mesopic range. The results show that a model employing a veiling luminance equation for the peripheral view field can predict the adaptation state in high adaptation level adequately, while the model does not work well in low adaptation level.
